A 16 sided polygon
If the interior angles add up to 1800 degrees then it is a 12 sided polygon.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
180 - interior angle = exterior angle
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
Each interior angle will measure 156 degrees
Each interior angle will measure 162 degrees
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Providing that it is a regular polygon then each interior angle will measure 160 degrees
Im stuck on that too :/
In geometry, an interior angle is an angle formed by two sides of a simple polygon that share an endpoint, namely, the angle of the inner side of the polygon.
